Abstract
The effect of pouring temperature on thixotropic microstructure of AZ91 was investigated. The results show that the pouring temperature has a pronounced effect both on microstructural morphology and grain size. By decreasing the pouring temperature, the morphology of grains changes from coarse dendritic to fine dendritic structure. The fine dendritic structure that was obtained at low pouring temperature developed into a globular structure with a grain size of 60 pun, if the AZ91 was partially remelted and held isothermally at the semisolid state (575 degrees C). On the other hand, if the alloy was poured at a high superheat, the particles were irregular and interconnected with a grain size of 180 mu m even after 20 ruin of isothermal holding
